Mantus Marine Small boats require a small, lightweight anchor that sets reliably in a variety of bottom soil conditions, and none of the currently available small anchors offer this level of performance. These models are easily collapsible without the need for bolts, which makes for easy storage; the shank slides into the fluke and needs only a single pin to lock and now features a removable roll bar, so quick assembly and disassembly are possible for storage in tight lockers. 2.5 lbs Stainless Steel – for boats up to 16 feet (No bolts needed for assembly, spring loaded pin locking mechanism) The ladder folds for easy storage, connects to a boat eye to easily climb out of the water. New this is a $399 package.
